Currently we have many dog training aids and management devices and many views on their effects on dog welfare. In the case of the e-collar studies are now being conducted, many years after their introduction to assess their welfare impact on dogs (and other animals).
What would happen if all new training or management devices had to be assessed (at the inventors expense) before being passed as legal for use ?
Would this be a good thing? Or would it merely restrict new training technologies and devices?
